Possible Hardware Error ?

cpe111

Just received my lab and am configuring a 3 lab exercise.

Placed aWC1T into W0 in a 2611XM. The router sees the serial card and allows me to issue configuration commands for S0/0. After configuration the interface will not come up

show ip interface brief shows Status = down, Protocol = down for S0/0.

I now power down the router, place the card into W1 and then power the router back up. I do not perform any additional configuration. Now the interface starts as expected.
show ip interface brief shows Status = up, Protocol = up for Serial 0/0.

How can this be - I would have expected the WC1T in W1 to have be S0/1?

Can anyone explain what is happening here?

Does this indicate a hardware problem with W0?

thanks,

Fault cable? Do u have another to check?

The cable works when moved from w0 to w1 - I just removed the entire WIC1T and attached cable from w0 to w1. Doesn't work in w0 does work in w1 - bit the weird thing is why does the router think the WIC-1T is S0/0 when its in W1 - shouldn't it be S0/1 ?

Whats the config ?

Tried saving the old config to your pc (tftp), then erase it and start from scratch ?
